This is a bit complicated actually.

Max-width or max-height is important to consider when wrapping items into flexbox lines. But always restricting line lengths to specified max size is not correct either.

If parent layout is also a flexbox, it will need to know max-content without min/max-width/height constraints, of flex algorithm will produce incorrect results.

This step of the algorithm (step 4) needs to mention min/max, but also note that parent layout must be able to suppress that.
